Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed March 16, 1920. Serial No. 366,228.

T 0 all whom it mag concern Be it known that 1, PETER R. THIBAULT, a citizen of the United States, and a resident oi St. Ignace, in the county of Mackinac and State of htlichigan, have invented certain new and useful Improvements in Churns, of which the following is aspecifi cation.

My present invention relates generally to churns, and more particularly to that type of churn employing a stationary body and a rotating paddle, more especially a body having double walls forming a liquid cooling chamber therebetween, my object being the provision of certain refinements as regards both the construction of the body and the paddle calculated to promote more ready manufacture and more el'licient results.

In the accompanying drawings illustrating my present invention and forming a part of this specification,

Figure 1 is a perspective proved churn complete,

Fig. 2 is an end elevation,

Fig. 3 is a vertical longitudinal section,

Fig. 1 is a vertical transverse section,

Fig. 5 is a detail perspective view of the paddle, and V Fig. 6 is a detail perspective view paddle crank.

Referring now to these figures my invention proposes a churn body including end walls 10 whose lower portions are rounded and whose upper portions are connected in a rigid manner by rails 11 forming portions of the side walls. The remaining or lower portions oi the side walls, and the base of the churn body are constituted by spaced parallel inner and outer sheet metal walls 12 and 1 3, whose upper edges are secured lengthwise along the inner and outer surfaces respectively of the side rails 11. The ends of the outer wall 13 are secured along the lower edges of the end walls 10, while the ends of the inner wall 12 are extended within recesses let in the inner suracesof the end walls as seen in Fig. 3 paralleling the lower edges of the end walls.

In this way it is obvious that assembly of the various parts oi the frame of the body as thus described becomes ready and simple, and the application of supporting legs 15 secured to the lower side portions of the end walls is facilitated.

The upper open end of the body is closed by a cover 16 having a handle 17, and by view of my imof the removing this cover the: material to be churned may be introducec within the body. l then the churning operation is completed the buttermilk is drained through an opening 18 in one of the. end walls above the inner plate 12, and water previously introduced through an opening in one of the end walls closed by a plug 19 and as seen in Fig. 2. may be drained through an opening 20 as seen in Figs. 3 and d normally closed by a plug 21 as seen in Fig. 1.

The end walls 10 have longitudinally alined socket plates or bearings 22, one of which extends completely through its re spective end wall and is provided with an outer pivoted latch piece 23. lhe paddle is of rectangular 'l'orm, constituted by rectangular strips 2% having reduced lapping and connected ends as at 25, one of which strips has a laterally projecting pin 26 and the other of which has a socket 27 alined with said pin. 'll hen the paddle is introduced within the churn the pin 26 is in serted in one of the socket or bearing members 2-2 and the socket 27 receives the inner polygonal end.28 of a crank 29 provided with a handle 30 having an annular groove 51 intermediate the ends of its shank for engagement by the latch piece 28 in order to hold the crank in operative connection with the paddle and still permit of free rotation thereof.

It is obvious from the foregoing that in addition to the ease and simplicity oi as sembling the body of my improved churn, it becomes a ready simple operation to thoroughly clean the same after using, partic ularly in view of the ready removal of the paddle by lifting the latch piece 28 and withdrawing the crank and then removing the paddle with its pin 26 from the body.

Thus to the extent described and shown it is obvious my invention provides certain structural refinements adapted to promote more ready manufacture, reduced cost, and more effective operation.

I claim:

1. A. churn having a body including end walls whose lower ends are rounded, side strips connecting the upper portions of the end walls, and inner and outer plates forming the base and the lower portions of the side walls of the body and whose upper longitudinal edges are secured to the inner and outer surfaces oi the lower portions of said side strips whereby to form a space be tween them equal to the thickness of the said side strips, the ends of the outer plate being secured to the lower curved portions of the end walls, and said end walls having grooves paralleling the said lower edges and receiving the ends of the inner plate as described.

2. A churn including a body having upper end walls whose lower portions are rounded 10 and whose inner surfaces have grooves paralleling the rounded lower edges thereof, side strips connecting the upper side portions of the said end; walls, and inner and outer spaced apart plates Whose upper edges are 15 secured to the inner and outer surfaces retween the upper portions of said plates, and

plugs normally closing the said openings as described.
